TextPattern.CapStyleAttribute Field

Identifies the CapStyle attribute of a text range.

Namespace:  System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

public static readonly AutomationTextAttribute CapStyleAttribute

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in TextPatternIdentifiers.

UI Automation clients get the value of the attribute by calling GetAttributeValue.

Values for this attribute are of type CapStyle. The default value is None.

The following example shows how to obtain an attribute value for a range of text in Microsoft Notepad.

NoteNote:

Microsoft Notepad is used as the text provider for example purposes only. Microsoft Notepad is not guaranteed to support the attribute value being requested.

private void GetCapStyleAttribute()
{
    // Start application.
    Process p = Process.Start("Notepad.exe", "text.txt");

    // target --> The root AutomationElement.
    AutomationElement target = AutomationElement.FromHandle(p.MainWindowHandle);

    // Specify the control type we're looking for, in this case 'Document'
    PropertyCondition cond = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document);

    AutomationElement textProvider = target.FindFirst(TreeScope.Descendants, cond);

    TextPattern textpatternPattern = textProvider.GetCurrentPattern(TextPattern.Pattern) as TextPattern;

    if (textpatternPattern == null)
    {
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.");
        return;
    }

    Object oAttribute = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.CapStyleAttribute);
    if (oAttribute == TextPattern.MixedAttributeValue)
    {
        Console.WriteLine("Mixed cap styles.");
    }
    else
    {
        Console.WriteLine(oAttribute.ToString());
    }
}
Private Sub GetCapStyleAttribute()
    ' Start application. 
    Dim p As Process = Process.Start("Notepad.exe", "text.txt")

    ' target --> The root AutomationElement. 
    Dim target As AutomationElement = AutomationElement.FromHandle(p.MainWindowHandle)

    ' Specify the control type we're looking for, in this case 'Document' 
    Dim cond As PropertyCondition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)

    Dim textProvider As AutomationElement = target.FindFirst(TreeScope.Descendants, cond)

    Dim textpatternPattern As TextPattern = CType(textProvider.GetCurrentPattern(TextPattern.Pattern), TextPattern)

    If (textpatternPattern Is Nothing) Then
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.")
        Return 
    End If 

    Dim oAttribute As Object = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.CapStyleAttribute)
    If (oAttribute = TextPattern.MixedAttributeValue) Then
        Console.WriteLine("Mixed cap styles.")
    Else
        Console.WriteLine(oAttribute.ToString())
    End If 
End Sub
